interaction examples

An introduction to LittleBits aimed at small (wearable) sensory action-reaction type of circuits.
Goal is to demonstrate some inputs (sensors) and outputs and how they could be combined.
Of course, experiment freely by mixing inputs & outputs!

Inputs

First, we introduce some possible inputs for an 'interaction game'.
Of course the circuits have outputs too, because otherwhise we wouldn't be able to sense what the inputs do.

Remote trigger i7

'Sense' when something comes close, uses infrared light emitted by ir-led. Led will turn on when trigger senses light from an ir source, of for instance, a tv-remote.
In this example we use a ir led (o7) to trigger the sensor.

Considerations: in a well-lit room both parts have to be close and aligned. Might work better in dark. 'tune' it with the oscillator (waveform = square).

Sound trigger i20

Respond to sound. If the volume (dBs) goes over the set limit, output can be triggered. Output in this example (first image) is generating a tone (using an oscillator i31) out of the speaker (o24).
To make it more fun, add a sequencer i22: see second image (set knob to 1 - random).

Considerations: adjust sensitivty of sound trigger (dB level) with the mini-screwdriver.
Adjust generated tone with tune and pitch knobs and set the waveform to square.

Outputs

In the previous section there were already some outputs suggested, but here are a few more.
These are chosen because they may influence the inputs from the previous section and therefore are suitable for a action-reaction kind of game.

Blinking led o1

Considerations: use the oscillator to tune: select waveform to square or saw, adjust pitch to make it blink faster or slower (frequency).

Wearable circuits

LittleBits circuits can be made wearable easy by strapping them to clothes.
You can for instance use elastic straps, (Velcro) tape and the hook and loop shoes that come with LittleBits.
